BOILER ATTACHMENT.

SPECIFICATION formingpart of Letters Patent No. 629,216, dated July 18, 1899.

Application filed January 30, 1899. Serial No 703 ,861. (No model.

especially designed for the collection and removal of sediment, the attachment being simple and durable in construction, very effective in operation, and readily applicable to locomotives and portable and stationary boilers.

The invention consists "of novel features and parts and combinations of the same, as

will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of my invention is I represented'in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures. Figure 1 is an end elevation of the i m provement as applied to a locomotive-boiler. Fig. 2 is a longitudinal sectional elevation of the same on the line 2 2 in. Fig. 1. Fig. 3 is an inverted plan view of the same. Fig. 4: is an enlarged sectional side elevation of part of the improvement on the line 4 4 in Fig. 3, and Fig. 5 is a transverse section of the same on the line 5 5 in Fig. 3.

The improved boiler attachment is provided with a pipe-line A, arranged under the boiler B and supported therefrom by hollow supports 0, which also serve to connect the interior bottom portion of the boiler with the pipe-line A, so that any sediment sinking-to the bottom of the boiler can pass by the said supports into the pipe-line A to accumulate therein and to .be blown out therefrom from time to time, as hereinafter more fully described.

Each of the supports 0 screws in a lug A on top of the pipe-line A and also screws into the shell of the boiler B, as is plainly illustrated in Figs. 4 and 5, and the said support is introduced through an apertured lug A in the bottom of the pipe-line, which apertured inside of the pipe-line concentric the inside of the pipe.

into position in the lug A and the boilershell I provide the lower end of each support with a square offset 0 for the application of a Wrench or like tool to turn the support, the latter being. also provided next to the square ofiset with a flange C beveled on thetop and fitting a corresponding connterbore on the to thelug A to'prevent leakage.

It is understood that when the plug D is re-' moved from the lug A the support can be readily placed in position to support the pipe- ;line from the boiler-shell'andconnect the bottom portion of the interior of the boiler with In order to close the supports 0, I provide a plug-valve E, carried on one side of the pipe-line, as is plainly indicated 'in Fig. 5, to disconnect the interior 'of the'boiler from the pipe-line whenever desired.

As shown in the drawings, the pipe-line is made rectangular under the fire-box portion of the boiler, the supports running fromthis rectangular part to the water-compartment or legs of the fire-box part of the boiler.

A siny gle branch extends under the forward part of the boiler, and this branch is likewise conn'ected by supports with the boiler-shell, as will be readily understood by reference to Figs. 2 and 3. The rectangular front or end of the pipe-line A is provided with two upv wardly extending branch pipes F, having horizontal extensions F passing to the inte V rior of the boiler directly over the crown-sheet B, the extensions F having slots or openings F to permit sediment at this part of the boiler to pass into the extensions and from the same by way of the branch pipes F into the pipe- .line A. The latter is provided at one end drawn through the supports into the pipe-line and forced out of the same by the action of steam.

By the use of the apparatus described the boiler can be kept free from mud, dirt, and other impurities contained in the water to insure long life to the boiler and a proper generation of steam without waste of fuel.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. A boiler attachment comprising a pipeline under the boiler, and hollow supports arranged for supporting the pipe-line from the boilerand forconnecting the interior bottom portion of the boiler with the pipe-line, to allow the sediment to pass from the boiler by way of the supports into the pipe-line, to accumulate the sediment in the pipe-line, and a blow-out device for removing the accumu lated sediment from the pipe-line, the said device comprising a blow-off valve in the pipeline, and a steam-pipe connection between the pipe-line and the steam-space of the boiler, substantially as shown and described.

2. A boiler attachment provided with a pipeline, and hollow supports for connecting the pipe-line with the boiler, each support having a square offset and an annular beveled flange for engaging the pipe-line at the inside, the pipe-line being'provided with a screw-plug opposite the support, to permit of the introduction and removal of the support, substantially as shown and described.

3. Aboiler attachment provided with a pi peline, and hollow supports for connecting the pipe-line with the boiler, each support having a square offset and an annular beveled flange for engaging the pipe-line at the inside, the pipeline being provided with a screw-plug opposite the support, to permit of the introduction and removal of the support, and a plug-valve carried by the pipe-line for opening or closing the said support, substantially as shown and described.

4. The combination with a boiler having a shell, and a furnace located in the shell with a space between the sides of the furnace and-the shell, of a pipe-line run beneath the boiler and having connection at one end with the steam-space of the boilerand having a blow-out at the other end, and hollow supports serving to sustain the pipeline and establishing communication between the same and the interior of the boiler at a point between the sides of the furnace and the interior of the shell.

5. An attachment for boilers, comprisinga pipe-line run beneath the boiler and having communication at one end with the steamspace and having a blow-out at the other end, hollow supports serving to sustain the pipeline and to establish communication with the same and the lower portion of the boiler,-aud a branch in communication with the pipe-line and extending upwardly into the boiler and having openings adjacent to the crown-sheets thereof.
